Firstly I'm not a pro but I found that I got bored of the seeing the same basic articles month on month, e.g. take fantasic landscapes - use a polarising filter and or a ND grad and make sure you include some foregrount interest etc.
I started to get Professional Photographer and Digital Photo Pro (which I now subscribe to) as the articles were far more interesting. Both include some awe inspiring portfolios as well as some basic business tips and ideas along with workflow tips and hints. They both also include the standard product tests usually of the more expensive kit as well as stuff with pretty extreme kit e.g. this month Professional Photographer has an article on a fashion shoot taken with the specialist Fuji IS Pro (infrared and UV sensitive digital SLR)
